In attempting my Year of Open Source, I’m dealing with some very complicated, hi-tech issues. My open hardware smartphone arrives tomorrow, I’m trying to build a microphone pre-amp, & I’m about to learn how to program a microcontroller. But how do the ideas of open hardware and free software apply to lo-tech products? Laundry powder, for example? You don’t see detergent brands taking each other to court over patent breaches, the products have hardly changed in decades, and the manufacturing process is not protected. No problem there. But at the same time you don’t get the recipe on the back of the box, you’re not encouraged to try to make laundry powder yourself, and to most people, that strange white powder with the blue flecks and the lilac scent is a complete mystery. Even if it does have oxi-action, enzymes and a freshness blast.

Time to start investigating. I had seen an alternative to laundry powder at the local organic store – soapnuts, the fruit of the soapberry tree, which you throw in your machine and somehow, apparently, your clothes come out clean. I assumed it was some kind of homeopathic magic beans scam.

I did some serious research before buying. Sure, there’s some pseudoscience and misleading claims about soapnuts around the place- did you know “there is evidence they were used to cure hysteria”? But for washing clothes, they’re legit. Soapnuts contain saponins, a chemical compound whose structure, like soap, has a fat-loving end and a water-loving end, allowing oil and grease to be surrounded by water molecules, breaking them apart and allowing water to better penetrate material. Saponins effectively break up the surface tension of water and allow clothes to get ‘wetter,’ making it easier to rinse off dirt when agitated.

Great! Soapnuts! No recipe required! Open source, right? Well… I can’t grow soapnuts here in Berlin, I’m still at the mercy of the market – there’s only one type of soapnut available, and I can’t change them to suit my preferences or the water in my area. Nor have soapnuts taught me what laundry detergent actually is or how it’s made. In order to address these issues, I decided to make my own washing powder as well.

A quick online search will tell you that you need three ingredients: washing soda, borax, and soap. An in-depth search will tell you that as of 2010, borax is a restricted chemical in the EU, prolonged exposure can cause reproductive problems, and it is no longer sold to the general public. Baking soda is a good replacement.

Here I needed to set myself some limits – just how DIY should I go? Do I want to collect a bucket of seawater, dig my own limestone, and make washing soda at home? To keep it simple I thought I’d stick to making the soap. But what is soap? Where does it come from? Is it dug from the lavender-scented soap mines of central Africa? I knew there was some kind of oil involved, but I’d never really given much thought to how it’s made or what it contains. Back to Wikipedia!

As it turns out, there are many different fats and oils you can use. Olive oil, tallow, lard, seed oils – and in the past, soap was made from all kinds of animal fats – whale oil, penguin oil, seal oil, you name it – if it’s cuddly, it can be turned into soap. An advantage of making your own soap is that you can use whatever fats happen to be locally abundant – in Greenland you could whip up a pungent walrus blubber soap, in Samoa coconut fat would do nicely, and here in Berlin I guess you’d go for pig fat and rapeseed oil. But for now I’m just using a generic recipe to learn the process.

The core idea behind soap making is mixing fatty acids with a strong alkaline solution, lye, which react to form a salt: soap. Lye is made from water and sodium hydroxide, a highly caustic compound used as drain cleaner, and bizarrely, also used for glazing pretzels.

My local chemist told me that yes, they had sodium hydroxide, but no, they would not sell it to me. It was “too dangerous”, and I was likely to injure myself. I explained that I had protective equipment, an understanding of the dangers, and a reasonably sane mind, but it was no use. Luckily, online sellers asked no questions about my mental state and were quite happy to ignore any threat to my well-being. Excellent.

When making soap, safety comes second only to style.

I found a simple recipe online, dressed myself handsomely in apron, gloves and safety goggles, and got mixing. It’s a fascinating process – the furious heat of the chemical reactions, the choking, lung-burning lye fumes (hold your breath), the slow transformation from oily liquid to a bubbling gloop. As it turns out, it’s much easier than I expected – it only took 15 minutes or so, and I somehow avoided searing my flesh with chemicals.

Soap-making is a little cheaper than buying commercial soap, and now I’ve found out how easy it is, I can start to have some fun with it. I’m keen to try different recipes – a hot-process version that you can use without weeks of curing, something using locally available oils, experiments with different fragrances. Who says soap must smell like potpourri? Now I’m free to make any fragrance I like. Maybe I could make my millions selling authentic Berlin soap to tourists – with the delicate aroma of cheap beer, cigarettes and currywurst. Look out for an open-sourced recipe soon…

Even if you don’t want to go through all the excitement of making soap, you can still save yourself a few bucks and have some fun making your own laundry powder. Grate a bar of laundry soap, add a cup of washing soda, half a cup of baking soda, and voila. It does look a lot like freshly grated parmesan, so maybe label the container to avoid any foamy pasta mix-ups.

On August 1st, Berlin-based filmmaker Sam Muirhead is abandoning traditionally copyrighted products and switching to Open Source software, hardware, and services for one year, as the subject of his own series of online documentary videos.

Sam Muirhead aims to raise awareness of open source projects and methods, and get people from outside the tech world interested and involved in Open Source.

“As someone without a background in high-tech, I want to show people that Open Source is not just for hackers – it is an idea that can be adapted to any aspect of life.”

The internet has changed the film world immensely, and created new means of funding, production and distribution. Utilising these new methods, Muirhead is exploring another big idea from the internet, Open Source, and its growing effect on the ‘real’ world.

Open Source originated in the world of software, with the Firefox web browser, Linux operating system, and much of the underlying structure of the Internet itself being collaboratively developed and released under Open Source licenses. But Muirhead is interested in the philosophy of Open Source – as an alternative to the traditional use of copyright and patents, it gives access to the plans and design used to make a product. This means users can adapt the product to their own personal needs or redistribute it. The idea has already spread from software to other areas, from Wikipedia to robotics to tractor design.

Muirhead will be taking the software development approach of ‘release early, release often’ to documentary making. With new videos and projects to be released every week, the result will be an evolving portrait of Open Source, and will enable the community to get involved in the project as it progresses.

Muirhead will make his own Open Source shoes, jeans, toothbrush and furniture (and release the designs for others). He’ll be using Open Source educational methods to learn Turkish, avoiding food grown from copyrighted seed strains, and abandoning Apple software.

When asked what he hoped to achieve by only using Open Source solutions for everything in his life, Muirhead stated, “Open source is a fascinating way of collaborating, of creating, and working together for common goals, but it’s seen by most as something only relevant to software. By bringing it into ‘real life’ and adapting it to everyday purposes, I hope to get people thinking about how Open Source could work in their lives.”

Muirhead suggests there’s a journalistic approach too: “I want to highlight the problems of the current copyright and patent system. Every week you see Apple, Samsung and Google throwing million-dollar lawsuits at each other, when technologically they all have shared goals. Whereas in the Free Software and open hardware community there’s the adage that competitors stand on each others’ shoulders, not on each others’ toes.” The project will be highlighting the achievements and methods of companies and individuals working with Open Source, and discussing their different business models.

Sam Muirhead is a music video director, editor and documentary maker from Auckland, New Zealand, with a background in web-based, festival and broadcast media.
